Some seriously manly storage from the 1950s & 60s

What follows are pictures of hard drives.

Really, really big ones.

From the 1950s and 1960s.

For no other reason than simply because they look awesome. Enjoy.

1956: The IBM RAMAC

Check out this beauty. The first commercial hard drive. "Random Access Method of Accounting and Control": RAMAC.

See those platters? Each one is 24 inches in diameter. Two feet! And there's 50 of them!

Dimensions: 5' high x 6' wide

Weight: Over one ton

Total capacity: 3.75 MB

And here she is being loaded onto an airplane.

I mean... dang. What if that hard drive fell over? "How'd he die?" "He was crushed to death by a hard drive."

Here's a few more pictures. Because it's awesome.

The IBM 305 RAMAC, the First Computer with a Hard Drive: $10,000 perMegabyte : History of Information

1961: Bryant Series 4000

Here is a personal favorite of mine (doesn't everyone have favorite 60 year old hard drive models?): The Bryant Series 4000.

Dimensions: 52" x 70" x 70"

Total capacity: Variable (see chart below) -- up to 205 MB!

Seriously. Up to 205 MB. In the 1960s! How crazy is that!

But then you look at this picture below... and it all makes sense. Those are some big, stinkin' platters! 39 inches in diameter... and it could hold up to 26 of them!

I mean... whoah! I wonder what sounds that drive made when seeking and reading data...

1962: IBM 1311

The IBM 1311 packed in six 14" diammeter platters into a single "disk pack". And each 10 lbs disk pack was removable. Making this a removable hard drive system. Pretty nifty.

Dimensions: "About the size of a top load washing machine"

Total capacity: "2 million characters" or "25,000 punch cards" (this was heavily marketed at replacing punch cards)

IBM Archives: IBM 1311 head assembly

IBM Archives: IBM 1311

I tell ya.

They just don't make 'em like they used to.

The futility of Ad-Blockers

Ads are filling the entirety of the Web -- websites, podcasts, YouTube videos, etc. -- at an increasing rate. Prices for those ad placements are plummeting. Consumers are desperate to use ad-blockers to make the web palatable. Google (and others) are desperate to break and block ad-blockers. All of which results in... more ads and lower pay for creators.

It's a fascinatingly annoying cycle. And there's only one viable way out of it.

openSUSE says "No Lunduke allowed!"

Those in power with openSUSE make it clear they will not allow me anywhere near anything related to the openSUSE project. Ever. For any reason.

Well, that settles that, then! Guess I won't be contributing to openSUSE! 🤣

You know, I've forgotten how much I enjoy hanging out here. :-D

I love that @Lunduke continues reporting the news that isn't getting reported anywhere else. Sometimes it gets old - another foundation or whoever goes hard left, another tech legend got banned, another system gets hacked, etc. But it's important enough that I still want to follow it. And he still works in some fun stuff too (like his ReactOS piece, which kinda has me wanting to create my own Linux distro with a fully Win32 userland). :-D

But he's not the only one creating awesome stuff on here! In case you're not aware...

@Greg_Gauthier has not one, not two, but three channels going! Old Computer Nerd, Old Sci-Fi Nerd, and Old Philosophy Nerd. I just spent like 2 hours following along on this cool "let's do a type-in BASIC program" video. More on that later.
@Dirt2901 posts random YouTube videos that always lead to fun! Whether it's new emulators, computing history, tutorials, or random stuff like "hard to ...

Listen To the AI Signal, not the Slop Noise

I wrote about my weekend trying out OpenClaw (formerly Clawdbot) and concluded that it was not yet valuable to me - given my current skill level, llm budget and the early results.

So many people on X are talking about the amazing things their autonomous OpenClaw bot is doing for them - enough to get me to try it. But my results didn’t match their in the time I allotted for the experiment.

THEN - DHH (the Ruby on Rails, Baecamp, HeyMail, Omarchy guy) posted this:

And followed it up with this:

How’d he get such better results than me? He’s more talented than I am. This is a good example of paying attention to the signal, not the noise.

Are the people hooking up their OpenClaw boots to “Moltbook” the signal? No, that’s noise. Yes, it’s absurd and crazy dangerous. And yes, most of the truly spooky stuff on there are actual humans pretending to be bots.

But the proof of the pudding are not the idiots. And it’s not...

$89 Lifetime Offer Ends at Midnight!

I’ll make this quick: The $89 Lifetime Subscription offer for The Lunduke Journal ends at midnight tonight (Saturday, January 31st).

Once the calendar reads “February” — poof — the deal is gone.

If you wanted to save 70% on a Lifetime Subscription, these are your final hours.

A huge thank you to everyone who has signed up during this crazy deal. We are this close to filling up the 4th Lifetime Subscriber Wall (there’s a possibility it might fill up in the next few hours).

Far beyond anything I was expecting. All of you are absolutely amazing. The Lunduke Journal would not be possible without you.

If you were on contemplating grabbing that Lifetime Sub, I’d jump on it right now. The price goes back up to normal ($300) in about 12 hours or so.

Get it while it’s cheap!

The End of the $89 Lifetime Sub is Nigh!

Quick reminder: The massive deal The Lunduke Journal has been running — 70%+ off Lifetime Subscriptions, 50% off all other subscriptions — ends after tomorrow (Saturday, January 31st).

Considering that, here are the steps I recommend:

Grab the $89 Lifetime Subscription before it ends tomorrow night.
High five yourself for saving money and supporting Indie Tech Journalism.
Maybe… grab a donut?

That is all.

$89 Lifetime Lunduke Subs ends this week!

Quick heads up, that the $89 Lifetime Subscription to The Lunduke Journal discount ends… at the end of this week!

Discounting Lifetime Subscriptions by over 70% was an absolute blast. So many of you took advantage of the offer that we’re now up to four Lifetime Subscriber walls at the end of every video. Crazy!

But something that awesome can’t last forever. Which means that, in just a few days, Lifetime Subscriptions will return to their regular price of $300.

With no plans to do another wild discount like that any time soon.

So.

If you haven’t already, snag an $89 (via Bitcoin) or $99 (via Substack or Locals) Lifetime Subscription.
Then let me know if you’d like to be added to the Lifetime Wall of ~~Shame~~ Awesomeness.

My guess is, a the current rate, that 4th Lifetime Wall will be full by Friday.

Bonkers.

And, once again, thank you to each and every subscriber. The Lunduke Journal would not be possible without you.
